ROBERT MALCOM, OF CHICAGO, ILLINOIS GOGGLE :HEADBAND FASTENING MEANS Application med October 17, 1930. rSerial No. 489,275.

My invention relates to means for securing the head hands to the eye-cups of a goggle; the object of the invention beino' to provide inexpensive means which enailes the ends of the head-band, Whether of elastic or non-elastic material, to be readily attached to the attaching members of the goggle without possibility of accidental dissociation Vof the parts; land at the same time to provide means whereby the free ends of the headbands or straps will be adjustably and at the same time lirmly secured together.

The objects and advantages of my invention will be more readily comprehended from the detailed description of the accompanying drawings, wherein- Figure 1 is a perspective view of a goggle provided with my improved attaching means; merely the ends ofthe head-bands being shown.

Figure 2 is a cross sectional View of one of the oye-'cups illustrating my improved attaching means with a portion of one end of the head-band and a portion of nose bridglng means being shown.

Figure 3 is a. perspective view of onerend of a head-band or strap with my improved attaching member or clip.

F igurc l is a sectional view taken sub- .'itantially on the line 1 4 of Figure 3.

Figure 5 is a plan view of the blank, cut and scored for forming the clip.

Figure 6 is a. perspective view of the clip partially bent ready t-o receive the end of She head-band therebetween.

Figure 7 is a detail sectional view taken substantially on the line 7 7 rof Figure 1 and showing in dotted lines the manner of inserting the clip in place.

As the eye-cups or goggle proper, asidel from the band attaching lug or ear, form no part of my present invention, a detailed description thereof need not be entered into.

In the specific eXempliiication of the in-l '.'en'tion, the outer side wall of each eye-cup 10 is provided with a cut-out portion yor ventilatino; opening as at 11. This opening, in order to prevent the entrance of foreign matter, is provided with a suitable mesh screen, as at 12, held by a suitable metallic rim or frame 13 whichlatter is provided with an integral ear 14 disposed ylaterally through The head-band, Which-is preferably of' more or less width, may either be composed of elastic material or non-elastic material and consists ofy two strapsv each having an end secured to one of the eye-pieces or cups -10 of the goggle. V

My improved attaching means. as disclosed in the drawings, consists of the clip 16 composed of sheet metal originally cut to the shape disclosed in Figure 5 consisting of a flat blank, with' the two opposite longitudinal sides provided with ears or lugs 18, 18 disposed at the vertical longitudinal center of the blank, while the other longitudinal opposite sides are preferably provided with the prong portions 19.

The blank,. after being cut to the form shown in Figure 5, is then scored and folded at its vertical aXis along the dotted line in dicated at 20 in Figure 5 into the condition shown in Figure 6, namely with the score and fold extending centrally through the ears 18, while the prongs are bent substantially at right` angles tothe same side or face of the blank. The prongs 19 on opposite ends or sides of the blank are olf-set or arranged in different transversev planes as shown in' Figure 5.

The end of the head-strap 17 is then inserted between the side walls 21, 21 and these two side walls Iirmly pressed together thereby forcing the prongs 19 kthrough the band lcausing the clip 16 to be firmly gripped to the end of the lstrap therebetween.

The slot in the ear 11 is of length just suilicient to receive the main portion ofthe clip 16; while the `width of the clip 16-at I ficient to permit the Jfolded clip with the end of the head-band to pass therethrough. The clip, attached to the end of the headband, is inserted edgewise through the slot, namely by :tlexing the strap and passing the narrow side of the clip through the slot, ai shown in dotted lines in Figure 7. It is apparent that as soon as the entire clip has been drawn endwisely entirely through the slot in the ear 1&1, the clip will immediately right itself into the full line position which will cause the ears 18 to engage with the forward outer side of the ear 14 and thus prevem. detachment of the head-ban d or strap 17. The construction shown and described, is apparent, is inexpensive in manufacture, while at the same time ensuring positive attachment of the head-band, preventing the latter from becoming accidentally detached or disconnected, but which will permit ot detachment of the head-band when found necessary by simply drawing the end of the head-strap suliiciently through the slot 15 in the ear 14 to permit the clip portion 16 to be placed into the angular relation disclosed in dotted lines in Figure 7 which enables the clip to be endwisely forced through the slot 15 of the ear 14.

In order to provide simple means whereby p the free ends of the head-straps 17 may be secured together into a head band of proper size to lit the head of the wearer, the straps 17 are shown provided with an elongated split ring 22, see Figure 1. This split ring is of size just suliicient to permit the ends of both straps 17 to pass therethrough, so as to hold the two straps in close frictional relation with each other. The end of each strap is preferably looped or folded and stitched into place so as to prevent the ring 22 slipping ott the straps. By positioning the ring 22, adjacent to the looped outer end of one strap, the other strap may be adjusted so as to provide a band of proper size for the wearer after the goggle has been applied, namely by shortening the end of one strap from ring 22 to the attached or clip end thereof. The ring' 22 causes the adjusted relation of the straps to be maintained; releasing of the straps being induced by grasping ring 22 and pulling on the shortened end of the strap until the band can be slipped 0H the head.

The speciiic embodiment of the invention has been described in terms employed merely as terms of description and not as terms of limitation, as structural modifications are possible without, however, departing from the spirit of my invention.

What I claim is:

1. In combination with the head straps of a goggle, holding means composed of a blank of sheet metal provided at its top and bottom marginal edges and intermediate of its ends with extensions, the blank being folded back upon itself with the ends of the straps therebetween.

2. In a goggle provided with head straps, a holding clip secured to each strap and composed of a flat sheet metal blank provided with opposingly arranged strap gripping surfaces, whilethe upper and lower marginal edges of the blank are provided with aligned extensions, the blank being folded about the strap end on a line disposed at the vertical axis of the blank through said aligned ez;- tensions.

3. In combination with the eye-cups of a goggle, each provided with a slotted ear, and head straps; of holding means secured to the ends or the straps and composed of a dat sheet metal blank, the upper and lower edges ofthe blank having aligned extensions, the blank being folded at its vertical axis through said extensions back upon itself with a strapend therebetween, the blank at its opposite side edges being provided with prong extensions bent at an angle to the blank, in opposing oset relation with each other and adapted to press into the straps, the folded end of the blank with said extensions being of width greaterthan the length of the slots in the cars.

ROBERT MALCOM.
